In felines, which tooth is the largest in the maxilla and how many roots does it have?

The largest tooth in the maxilla of felines is the maxillary fourth premolar, commonly referred to as maxillary 08. This tooth is significant not only for its size but also due to its role in the dental arc. It typically has three roots, which are essential for anchoring the tooth securely in the maxillary bone and supporting its function in chewing, especially when processing food. This structural configuration allows for greater stability and strength in the upper jaw, which is crucial for the animal's predatory lifestyle.

In contrast, the other options refer to teeth that are not the largest in the maxilla or do not have the correct number of roots associated with them. Understanding the anatomy and morphology of dental structures in felines is vital for veterinary professionals, especially when diagnosing dental issues or performing procedures such as extractions.
